GRE阅读找对中心句合理提速

篇1：GRE阅读找对中心句合理提速

GRE阅读提速从找准中心句开始

之所以强调中心句，主要还是为了应对GRE阅读考试的出题思路。大家需要明确的一点是，想要做好GRE长篇阅读，考生其实并不需要把整篇文章都读懂吃透才能解题。许多类似主旨题态度题的阅读题目，考生只要能够结合文章中心句大致理解整体意思就能毫无困难的解题。而文章中许多细节案例，其实往往都是毫无用处的过量信息，纯粹是为了消耗大家时间而故意挖下的陷阱。因此，面对长篇阅读，考生首先要做的不是读完全文，而是找到中心句加快理解速度。

篇2：GRE阅读找对中心句合理提速

那么，如何才能快速找到中心句呢?这里小编建议大家结合GRE阅读文章本身的类型来寻找，一般来说，GRE阅读文章可以大致分为三种类型，每种类型的中心句位置各有不同，考生需要根据文章类型来寻找中心句，具体如下：

A. 现象解释型文章

文章开始给出现象，之后必定有解释，中心句在解释给出处。若解释不止一个，中心句则为给予正评价的那个。

B. 新老观点型文章

中心句在新观点处(注意旧观点的取非)。

C. 问题解决方案型文章

中心句位于相应的解决方案处。

结合文章句型关键词寻找中心句

除了根据文章套路来找中心句外，大家有时候还可以根据文章本身的一些语言现象来找到暗示中心句所在的提示信息。

A. 一段叙述后有转折连词

but, yet, however, actually, in fact, indeed, virtually, practically等，中心句位于转折之后作者态度处。

B. 设问以及回答

作者的自问自答，中心句位于回答处。

C. 大段举例

举例前的理论说明或者之后的归纳易成为中心句。

总而言之，考生如果想在较短时间内更有效率地做好GRE阅读，特别是一些长篇阅读，那么找中心句的技巧就是必不可少的了。而上文中的内容，无疑将帮助大家更好地掌握这种技巧。

如何有效应对GRE阅读突然卡壳

建议1：原来英文基础不错，但是GRE阅读复习有他独特的逻辑结构和出题思路，所以有了好的英文基础，还必须去专门总结、反复练习达到对这种考试结构的敏感和熟练。

建议2：通过你的阅读训练难以克服GRE阅读，恰恰说明了我讲的第一点，GRE有他的特殊性，难句是克服阅读基本障碍的，之后就应该把注意力转移到针对GMAT的集中突破总结上，读外文期刊是细水常流练习阅读的方式，有限的复习时间里建议放弃，把时间转移到OG的集中突破总结上，当把所有OG(有时间+补充材料的阅读文章)总结4-5 遍以上，你自会有顿悟的。

建议3：别看简单，但是这种有针对性的总结对GRE阅读的领悟是很有帮助的，在几遍总结中，请注意加强原文逻辑结构的阅读;练习题干-选项-原文的对应关系的敏感度，即如何找到ETS给你藏好的答案，如何迅速排除错误答案。请一定读一遍我的阅读示范，会明白我讲的如何取舍的读文章，如何找答案的意思。 (参考Mumu阅读示范)

建议4: GRE阅读复习是逻辑和语法两项的基础，提高阅读也会给其他两项提速，如果其他两项做题时也有对整体逻辑框架把握不准做题慢的问题，那么不妨把更多时间用来阅读集中突破，其他两项为辅。

建议5：参考其他人的经验

良好的GRE阅读理解习惯培养方法

1.解剖文章的第1段

新GRE考试中阅读部分需要考生积极主动地解读文章的第1段，阅读时尽量记住作者提出的问题(现象或观点)，和一些关于文章内容的概念和词汇，如这篇文章讲的是生物化学，日本企业文化还是黑人运动。文章的论题是什么，作者想说什么-

2.在脑子里面形成一个作者思路图

在脑子里或者在草稿纸上画一个文章的结构思路题。各个段落的目的是什么，主题又是什么-再次提醒，考察的是你的答题能力而非阅读能力。你不必完全掌握整篇文章，了解文章中的每一个细节(其实，你也没有那么多时间)。相反，你应该只读文章段落的第1句，而快速浏览其余部分。当你“读”完这篇文章时，你就能对文章的结构思路有总体的把握。

3.通览文章时，留意语气词和过渡词

在快速阅读文章时，特别留意段落开头或者结尾可能出现的语气词和过渡词。这样做有助于你对作者思路的把握，从而快速掌握文章大意。

4.停下来，总结一下文章大意

在回答问题前，花几秒钟总结一下文章的思路和主题。

5.开始答题

根据你对文章的整体思路来答题。将问题(或选项)定位到文章中具体的某个段落甚至具体的句子。这里，你可以比第3个步骤更仔细。

GRE阅读练习每日一篇

The stratospheric ozone layer is not a completely uniform stratum, nor does it occur at the same altitude around the globe. It lies closest to the Earth over the poles and rises to maximum altitude over the equator. In the stratosphere, ozone is continuously being made and destroyed by natural processes. During the day the Sun breaks down some of the oxygen molecules to single oxygen atoms, and these reacting with the oxygen molecules that have not been dissociated, form ozone. However, the sunlight also breaks down ozone by converting some of it back to normal oxygen. In addition naturally occurring nitrogen oxides enter into the cycle and speed the breakdown reactions. The amount of ozone present at any one time is the balance between the processes that create it and those that destroy it.

Since the splitting of the oxygen molecules depends directly upon the intensity of solar radiation, the greatest rate of ozone production occurs over the tropics. However ozone is also destroyed most rapidly there, and wind circulation patterns carry the ozone-enriched upper layers of the atmosphere away from the equator. It turns out that the largest total ozone amounts are found at high latitudes. On a typical day the amount of ozone over Minnesota, for example, is 30 percent greater than the amount over Texas, 900 miles farther south. The density and altitude of the ozone layer also change with the seasons, the weather, and the amount of solar activity. Nevertheless, at any one place above the Earth’s surface, the long-term averages maintained by natural processes are believed to be reasonably constant.

The amount of ozone near the Earth is only a small percent of the amount in the stratosphere, and exchange of molecules between the ozone layer and the air at ground level is thought to be relatively small. Furthermore, the ozone molecule is so unstable that only a tiny fraction of ground-level ozone could survive the long trip to the stratosphere, so the ozone layer will not be replenished to any significant degree by the increasing concentrations of ozone that have been detected in recent years near the earth’s surface. The long-term averages of ozone both near ground level (ground level: n.[地质]地水准平面) and in the stratosphere are regulated by continuous processes that are constantly destroying and creating it in each of these places. This is why scientists are so concerned about human beings injection into the stratosphere of chemicals like nitrogen oxides, which are catalysts that facilitate the breakdown of ozone. If the ozone layer is depleted significantly, more ultraviolet radiation would penetrate to the Earth’s surface and damage many living organisms.

17. The passage suggests that factors contributing to the variation in the amount of ozone above different areas of the Earth’s surface include which of the following?

I. Some of the ozone found at higher latitudes was produced elsewhere.

II. There is usually a smaller amount of naturally occurring nitrogen oxide over high latitudes.

III. The rate of ozone production over the poles is less than that over the tropics.

(A) II only

(B) III only

(D) I and III only

(E) I, II, and III

18. Which of the following best states the central idea of the passage?

(A) Naturally occurring nitrogen oxides, as well as those introduced by humans, threaten to deplete the layer of ozone in the stratosphere.

(B) A delicate but reasonably constant balance exists between the natural processes that produce and those that destroy ozone in the stratosphere.

(C) There is little hope that the increased concentrations of ground-level ozone observed in recent years can offset any future depletion of stratospheric ozone.

(D) Meteorologically induced changes in the concentration of ozone in the stratosphere tend to cancel themselves out over a period of time.

(E) Solar radiation not only produces and destroys zone but also poses a hazard to human life.

19. The processes that determine the amount of ozone in a given portion of the stratosphere most resemble which of the following?

(A) Automobile emissions and seasonal fog that create a layer of smog over a city

(B) Planting and harvesting activities that produce a crop whose size is always about the same

(D) Assets and liabilities that determine the net worth of a corporation

(E) High grades and low grades made by a student whose average remains about the same from term to term

20. According to the passage, which of the following has the LEAST effect on the amount of ozone at a given location in the upper atmosphere?

(A) Latitude

(B) Weather

(D) Ground-level ozone

(E) Solar activity

21. The author provides information that answers which of the following questions?

I. What is the average thickness of the stratospheric ozone layer?

II. Why does increased exposure to ultraviolet radiation damage many living organisms?

III. What is the role of oxygen in the production of stratospheric zone?

(A) I only

(B) II only

(D) I and II

(E) II and III

22. In explaining what determines the amount of ozone in the stratosphere, the author describes natural processes that form

(A) an interactive relationship

(B) a reductive system

(D) a set of randomly occurring phenomena

(E) a set of sporadically recurring events

Feelings of hopelessness among medieval workers trapped in the poverty cycle gradually lessened as it became possible for women’s labor to supplement a family’s money income by more than pennies. By 1300, women spinners could be found working on their own (on one's own: adv.独自地, 独立地, 主动地) for wealthy sponsors, even after the introduction in Italy and France of prohibition against advancing money for supplies to women spinners. Historians have usually interpreted this prohibition simply as evidence of women’s economic subjection, since it obliged them to turn to usurers; however, it was also almost certainly a response to a trend toward differential reward for women’s higher skill. Yarn can be spun irregularly and lumpily, but perfectly smooth yarn is worth more. Working for merchant entrepreneurs on time rates, women had been paid hardly more than children; working as entrepreneurs themselves and producing good work by the piece, they could break into (to make entry or entrance into “broke into the house” “break into show business”) the rational system of differential rewards.

23. The primary purpose of the passage is to

(A) propose and defend a theory about the consequences of a certain historical event

(B) present historical facts and offer a broader interpretation of those facts than has been offered in the past

(D) demonstrate the superiority of using an economic approach to historical analysis

(E) call attention to the influence of the textile industry on society during a particular historical period

24. It can be inferred from the passage that the author views the system of paying all workers equally on time rates as

(A) unfair and not rational

(B) undesirable but unavoidable

(D) advantageous to most women workers

(E) evidence of a trend toward a more modern wage system

25. The passage implies which of the following about women spinners in medieval Europe?

(A) Most of them worked independently for wealthy sponsors.

(B) They were not typical of medieval women entrepreneurs.

(D) They would have been able to contribute substantial amounts to their families incomes were it not for the prohibition against advancing money to them.

(E) They were inevitably disadvantaged in the marketplace because they were obliged to obtain money for their supplies from usurers.

26. The passage implies that feelings of hopelessness among medieval workers

(A) resulted primarily from the lack of a rational system of differential rewards

(B) disappeared completely once medieval textile workers were able to break the cycle of poverty

(D) came into being in part because of women’s limited earning capacity

(E) were particularly common among textile workers in Italy and France

27. The author suggests that historians have done which of the following?

(A) Failed to give adequate consideration to the economic contribution of women during the medieval period.

(B) Overestimated the degree of hopelessness experienced by medieval workers trapped in the poverty cycle.

(D) Regard the economic status of women in Italy and France as representative of women’s status throughout medieval Europe.

(E) Overlooked part of the significance of a prohibition governing one aspect of yarn production in medieval Europe.

GRE阅读控速提速方法：词汇基础打扎实

做GRE阅读时，并不需要认识文章里的所有单词。如果章中一些名词不认识，可以去猜，练习猜词的能力，毕竟考试中肯定会有词不认识，要根据上下文推测下。

但是，如果是一些重要的形容词，名词，动词，那么还是要熟悉才行。因为这些词反映了作者的态度和文章转折等结构，所以要做到对这些词熟练认识，形成条件反射，一看到就能反应出词义。

建议可以去背下阅读类单词表，平时做阅读时对于重要的可以推理作者态度的词也总结背下来。

GRE阅读控速提速方法：每天练习长难句

建议各位考生保持每天都练习一下长难句，以不看答案，自己分析为标准。每看完一句长难句，都做一下相关训练，对提高阅读速度非常有帮助。看长难句最好每天都花一个小时，看的时候逐渐增加阅读速度。

GRE阅读控速提速方法：速度训练

很多教材都介绍了很多阅读把握逻辑框架的技巧，比如not only后的跳过，but also后的重点读，however后的要重点度之类的。建议大家不能盲目记这些技巧，最好亲手总结适合自己的方法，毕竟很多时候gre细节题考的都是一些要”跳过的“插入语，或者for example之后的内容。如果读的时候直接跳过了，就会有问题。比如一篇反驳老观点的阅读，看到第一个词many people，就可以扫过这句找however，因为however肯定是指出他的不足和他对比，通过however的观点，脑子里就可以推出many people 的观点，这样就可以略过不少内容。同时，一定要边读边动脑子，而不是盲目吸收信息。大家都知道新gre是逻辑考试，不是简答的语言考试，不要用做中学英语阅读的那套。如果阅读中遇到读不懂的长难句，就仔细破解，找主谓宾，静下心来破解。这样把握了结构做题的时候，遇到主旨题，细节题，作者态度题就可以直接解决，不用回头看文章，然后遇到细节题，回去快速定位找下，毕竟文章理解了，定位会很快。

GRE阅读控速提速方法：卡时间训练

以上就是GRE阅读控制解题速度和提速方法的介绍，希望大家都能在GRE阅读考试中把握好考试时间，顺利取得满意的成绩。

GRE阅读练习

The transplantation of organs from one individual to another normally involves two major problems: (1) organ rejection is likely unless the transplantation antigens (a usually protein or carbohydrate substance (as a toxin or enzyme) capable of stimulating an immune response) of both individuals are nearly identical, and (2) the introduction of any unmatched transplantation antigens induces the development by the recipient of donor-specific lymphocytes that will produce violent rejection of further transplantations from that donor. However, we have found that among many strains of rats these “normal” rules of transplantation are not obeyed by liver transplants. Not only are liver transplants never rejected, but they even induce a state of donor-specific unresponsiveness in which subsequent transplants of other organs, such as skin, from that donor are accepted permanently. Our hypothesis is that (1) many strains of rats simply cannot mount a sufficiently vigorous destructive immune-response (using lymphocytes) to outstrip the liver’s relatively great capacity to protect itself from immune-response damage and that (2) the systemic unresponsiveness observed is due to concentration of the recipient’s donor-specific lymphocytes at the site of the liver transplant.

17. The primary purpose of the passage is to treat the accepted generalizations about organ transplantation in which of the following ways?

(A) Explicate their main features

(B) Suggest an alternative to them

(D) Criticize the major evidence used to support them

(E) Present findings that qualify them

18. It can be inferred from the passage that the author believes that an important difference among strains of rats is the

(A) size of their livers

(B) constitution of their skin

(D) sensitivity of their antigens

(E) adaptability of their lymphocytes

19. According to the hypothesis of the author, after a successful liver transplant, the reason that rats do not reject further transplants of other organs from the same donor is that the

(A) transplantation antigens of the donor and the recipient become matched

(B) lymphocytes of the recipient are weakened by the activity of the transplanted liver

(D) transplanted liver continues to be the primary locus for the recipient’s immune-response reaction

(E) recipient is unable to manufacture the lymphocytes necessary for the immune-response reaction

20. Which of the following new findings about strains of rats that do not normally reject liver transplants, if true, would support the authors’ hypothesis?

I. Stomach transplants are accepted by the recipients in all cases.

II. Increasing the strength of the recipient’s immune-response reaction can induce liver-transplant rejection.

III. Organs from any other donor can be transplanted without rejection after liver transplantation.

IV. Preventing lymphocytes from being concentrated at the liver transplant produces acceptance of skin transplants.

(A) II only

(B) I and III only

(D) I, II, and III only

(E) I, III, and IV only

Practically speaking, the artistic maturing of the cinema was the single-handed achievement of David W. Griffith (1875-1948). Before Griffith, photography in dramatic films consisted of little more than (little more than: 和...无差别[一样]) placing the actors before a stationary camera and showing them in full length as they would have appeared on stage. From the beginning of his career as a director, however, Griffith, because of his love of Victorian painting, employed composition. He conceived of the camera image as having a foreground and a rear ground, as well as the middle distance preferred by most directors. By 1910 he was using close-ups to reveal significant details of the scene or of the acting and extreme long shots to achieve a sense of spectacle and distance. His appreciation of the camera’s possibilities produced novel dramatic effects. By splitting an event into fragments and recording each from the most suitable camera position, he could significantly vary the emphasis from camera shot to camera shot.

Griffith also achieved dramatic effects by means of creative editing. By juxtaposing images and varying the speed and rhythm of their presentation, he could control the dramatic intensity of the events as the story progressed. Despite the reluctance of his producers, who feared that the public would not be able to follow a plot that was made up of such juxtaposed images, Griffith persisted, and experimented as well with other elements of cinematic syntax that have become standard ever since (ever since: adv.从那时到现在). These included the flashback, permitting broad psychological and emotional exploration as well as narrative that was not chronological, and the crosscut between two parallel actions to heighten suspense and excitement. In thus exploiting fully the possibilities of editing, Griffith transposed devices of the Victorian novel to film and gave film mastery of time as well as space.

Besides developing the cinema’s language, Griffith immensely broadened its range and treatment of subjects. His early output was remarkably eclectic: it included not only the standard comedies, melodramas, westerns, and thrillers, but also such novelties as adaptations from Browning and Tennyson, and treatments of social issues. As his successes mounted, his ambitions grew, and with them the whole of American cinema. When he remade Enoch Arden in 1911, he insisted that a subject of such importance could not be treated in the then conventional length of one reel. Griffith’s introduction of the American-made multireel picture began an immense revolution. Two years later, Judith of Bethulia, an elaborate historicophilosophical spectacle, reached the unprecedented length of four reels, or one hour’s running time (running time: (程序)执行时间, 运行时间). From our contemporary viewpoint, the pretensions of this film may seem a trifle ludicrous, but at the time it provoked endless debate and discussion and gave a new intellectual respectability to the cinema.

21. The primary purpose of the passage is to

(A) discuss the importance of Griffith to the development of the cinema

(B) describe the impact on cinema of the flashback and other editing innovations

(D) analyze the changes in the cinema wrought by the introduction of the multireel film

(E) document Griffith’s impact on the choice of subject matter in American films

22. The author suggests that Griffith’s film innovations had a direct effect on all of the following EXCEPT:

(A) film editing

(B) camera work

(D) sound editing

(E) directing

23. It can be inferred from the passage that before 1910 the normal running time of a film was

(A) 15 minutes or less

(B) between 15 and 30 minutes

(D) between 45 minutes and 1 hour

(E) 1 hour or more

24. The author asserts that Griffith introduced all of the following into American cinema EXCEPT:

(A) consideration of social issues

(B) adaptations from Tennyson

(D) photographic approaches inspired by Victorian painting

(E) dramatic plots suggested by Victorian theater

25. The author suggests that Griffith’s contributions to the cinema had which of the following results?

I. Literary works, especially Victorian novels, became popular sources for film subjects.

II. Audience appreciation of other film directors’ experimentations with cinematic syntax was increased.

III. Many of the artistic limitations thought to be inherent in filmmaking were shown to be really nonexistent.

(A) II only

(B) III only

(D) II and III only

(E) I, II, and III

26. It can be inferred from the passage that Griffith would be most likely to agree with which of the following statements?

(A) The good director will attempt to explore new ideas as quickly as possible.

(B) The most important element contributing to a film’s success is the ability of the actors.

(D) The cinema should emphasize serious and sober examinations of fundamental human problems.

(E) The proper composition of scenes in a film is more important than the details of their editing.

27. The author’s attitude toward photography in the cinema before Griffith can best be described as

(A) sympathetic

(B) nostalgic

(D) condescending

(E) hostile

篇5：GRE阅读主题句怎么找

GRE阅读主题句怎么找?快速定位心得分享

GRE阅读中主题句常见形式

和国内学生写文章不一样，美国人的阅读文章中从来都不出现“I think that，in my opinion，as far as I am considered”此类语言做主题句。通常来说主题句有以下两种形式：

1. 判断句(含情态动词，系动词，正负褒贬词的句子);

2. 概括文章将来结构。

实例讲解主题句定位方法

以这句话为例：Your minds changed my attitude. 这句话中并没有情态动词和系动词，因此这句话自然不是判断句，也就不是主题句。但只要在这句话中加入一个正负褒贬词，即一个词表明作者的态度或观点的词即是判断句了。比如，Your minds successfully changed my attitude即是判断句了。

另外，如果一个句子不是判断句，只要它能够概括文章将来结构，及文章后面会从哪几个方面来说明，也是主题句。比如，People are living longer now. 这句话一定不是主题句，而如果这句话是，People are living longer now since the improvement of food condition and the development of medical technology.这句话即是主题句了。因为它概括了文章后面会从哪几个方向来进行说明。

学会快速定位主题句的实用价值

如果考生在新GRE阅读题中掌握好了主题句判断方法，很多文章便可以很快把握文章的结构框架，帮助后面文章的理解。

比如一篇文章的开头是，Mycorrhizal fungi infect more plants than do any other fungi and are necessary for many plants to thrive， but they have escaped widespread investigation until recently for two reasons. First， the symbiotic association is so well-balanced that the roots of host plants show no damage even when densely infected. Second， the fungi cannot as yet be cultivated in the absence of a living root.

第一句是明显的判断句，即为主题句。而主题句也同时概括了文章的将来结构，即会从“M真菌影响力很强”和“M真菌过去由于两个原因没有得到广泛研究”。下面马上看到了first和second，我们即知道这两个很难读懂的句子无非是两个原因使得M真菌没有得到广泛研究而已，具体是哪两个原因，我们几乎可以忽略不读。

综上所述，在做GRE阅读时，快速定位主题句的方法和技巧是非常实用的，希望大家都能学会掌握和运用这种技巧，提高选对选项的效率，节省考试时间。

GRE阅读例题：遥感技术的前世今生

The age at which young children begin to make moral discriminations about harmful actions committed against themselves or others has been the focus of recent research into the moral development of children. Until recently, child psychologists supported pioneer developmentalist Jean Piaget in his hypothesis that because of their immaturity, children under age seven do not take into account the intentions of a person committing accidental or deliberate harm, but rather simply assign punishment for transgressions on the basis of the magnitude of the negative consequences caused.

However, in recent research, Keasey found that six- year-old children not only distinguish between accidental and intentional harm, but also judge intentional harm as naughtier, regardless of the amount of damage produced. Both of these findings seem to indicate that children, at an earlier age than Piaget claimed, advance into the second stage of moral development, moral autonomy, in which they accept social rules but view them as more arbitrary than do children in the first stage. (163 words)

8.According to the passage, Piaget and Keasey would not have agreed on which of the following points?

(A) The kinds of excuses children give for harmful acts they commit

(B) The age at which children begin to discriminate between intentional and unintentional harm

(D) The circumstances under which children punish harmful acts

(E) The justifications children recognize for mitigating punishment for harmful acts

9.According to the passage, Keasey's findings support which of the following conclusions about six-year-old children?

(A)They have the ability to make autonomous moral judgments.

(B)They regard moral absolutism as a threat to their moral autonomy.

(C)They do not understand the concept of public duty.

(D)They accept moral judgment made by their peers more easily than do older children.

(E)They make arbitrary moral judgments.

The term ”remote sensing" refers to the techniques of measurement and interpretation of phenomena from a distance.

“遥感” 这个词涉及远距离测量及解读信息的技术。

Prior to the mid-1960's the interpretation of film images was the primary means for remote sensing of the Earth's geologic features.

1960 年代中期以前，地质学特征的遥感主要是通过对胶片上图像的解读。

With the development of the optomechanical scanner, scientists began to construct digital multispectral images using data beyond the sensitivity range of visible light photography.

随着光学机械扫描仪的发展，科学家开始用超越可见光摄影敏感范围的数据，构建多光谱数码图像。

These images are constructed by mechanically aligning pictorial representations of such phenomena as the reflection of light waves outside the visible spectrum, the refraction of radio waves, and the daily changes in temperature in areas on the Earth's surface.

这些图像的构建，要通过对一些现象进行机械校准，像不可见光的反射，无线电波的折射，以及该区域内地表温度的日常变化。

The advantage of digital over photographic imaging is evident: the resulting numerical data are precisely known, and digital data are not subject to the vagaries of difficult-to-control chemical processing.

数码图像相较于胶片感光成像的优势显而易见：由大量数据产生的结果更精确，而且数据不会受制于各种难以掌控的化学步骤。

8. It can be inferred from the passage that a major disadvantage of photographic imaging in geologic mapping is that such photography

(A) cannot be used at night

(B) cannot focus on the details of a geologic area

(D) is always enhanced by digital reconstruction

(E) cannot reflect changes over extended periods of time

选 C

细节题。

问传统办法的 major disadvantage 其实等于问新技术的 advantage，回到句 5：

细节题是不是可以不读文章直接用关键字回溯文段来节省时间?

我个人觉得不能，因为很多细节题的问法是相对隐蔽的，不读懂文段大意，定位经常可能不准，一个稍微精致的干扰就能让人中招。而这种方法之所以听起来不错，因为它和所有事后诸葛一样。所以，老实点，不要想取巧了。

虽然某些实验表明，随着一个物体变得熟悉起来，其内心再现图像亦更具整体感，辨认过程相应地更趋于平行，但证据的砝码似乎在支持序列假设(serial hypothesis)，至少是对于那些不甚简单、不甚熟悉的物体来说。

难句类型：复杂修饰、插入语、省略

解释：在Although引导的分句中，谓语shows后面跟着一个长长的宾语从句，从句中先出现一个插入语as an object becomes familiar,之后的内容是由and 连接的两套并列的主谓宾。其实and前后就是两个句子，只不过作者省略了后面的句子中与前面相同的引导词that和谓语become。

句子中有一个生词holistic，其实即使不认识，也能用合理化原则猜出它是后面serial的反义词、parallel的同义词，大约是统一、完整或同时的意思;其实只要能理解到其是与serial相反的意思即可。

意群训练：Although some experiments show that，as an object becomes familiar，its internal representationbecomes more holistic and the recognition process correspondingly more parallel，the weight of evidence seems to support the serial hypothesis, at least for objects that are not notably simple and familiar.

This preference for exogamy，Gutman suggests， may have derived from West African rules governing marriage，which，though they differed from one tribal group to another，all involved some kind of prohibition against unions with close kin. (3+)

难句类型：复杂修饰、插入语

译文：古特曼表示，这种对于外部通婚的偏爱很有可能缘起于西部非洲制约着婚姻的规定，尽管这些规定在一个和另一个部落群体之间不尽相同，但都涉及到某种对近亲联姻(union with close kin)的禁止。

解释：本句有两个插入语，第一个插入语Gutman suggests割裂了主句的主语和谓语。West African rules后跟着两个修饰成分，第一个是分词修饰(governing marriage), 第二个是以which引导的非限定性定语从句，从句中出现了第二个插入语though they differed from one tribal group to another，又割裂了从句引导词与谓语之间的联系。
